Specification of Letters Patent.

Patented July 17, 1906.

Application filed June 19, I905. Serial No. 265,902.

To all whom, it may concern- Be it known that I, J OI-IN J. REILLY, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a certain new and useful Pump, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to pumps of that class known as air-displacement pumps, the primary object of the invention being to provide a pump of the character referred to which will operate continuously and deliver a continuous stream of water at any desired point through a suitable service or supply pipe.

The pump contemplated in this invention is designed to be wholly or partially sub merged in the water or other liquid to be pumped and is used in connection witha suitable air-compressor, which latter controls the operation of the pump. The pump itself maybe located in any stream, and the point of delivery may be arranged at any desired distance from the pump. Under the preferred embodiment of the invention a plurality of pump-cylinders is employed and arranged in such manner that one or more cylinders are discharging while the remaining cylinders are filling, and vice versa, thus obtaining a continuous flow of liquid from the pump through the supply or service pipe to the point of delivery. Any desired number of pump-cylinders may be employed, according to the capacity desired. Where the required capacity is small, the pump may be constructed with a single cylinder.

With the above and other objects in view,

' the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination, and arrangement of parts, as hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a broken plan view of a duplex or two-cylinder pump embodying the present invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a plan view of the top or head of one of the cylinders, showing the seat for the airvalve chest and the ports therein. Fig. 4 is a bottom plan view of the air-valve chest. Fig. 5 is a sectional view through the valvechest and also through the upper portion of one cylinder, showing the valve-operating connections. Fig. 6 is a vertical section through the same, taken at right angles to Fig. 5. Fig. 7 is a longitudinal. section through the valve-chest, showing the piston: valve and the arrangement of ports. Fig. 8 is a horizontal section through the same. Fig. 9 is a vertical crosssection through the same, taken at right angles to Fig. 7. 10 is a sectional view of the piston-valve. Figs. 11 and 12 are respectively plan and side views of the auxiliary air-admission valve. Fig. 13'is a plan view showing a multiple-cylinder pump embodying the same principle. Fig. 14 is a plan view illustrative of a singlecylinder pump.

Like reference-numerals designate corresponding parts in all the figures of the draw ings.

The pump contemplated in this invention comprises a hollow base 1, preferably of oblong or rectangular form and of the requisite depth between its top and bottom walls to receive the necessary amount of water as it passes to and from the pump-cylinders, the water passing inward to the base through the main inlet 2 and passing outward from the base through the main outlet 3.

The inlet and outlet 2 and 3 are preferably arranged at opposite sides of the base, while hereinafter described, it being understood that all of the intake-valves are located on one side of the partition 4, while the discharge-valves are located on the opposite side of the partition.

Mounted upon and extending upward from the base 1 are pump-cylinders 5 and 6, each cylinder being provided in its bottom with a plurality of valves communicating directly with the hollow base. As shown in Fig. 1, each cylinder is provided with a pair of intake-valves 7 and a pair of dischargevalves 8. Each intake-valve, as shown in Fig. 2, opens inwardly, so as to allow the water to pass from the hollow base upward through the valve-opening into the cylinder, said valve preferably comprising a'hollow or perforated seat 9, while the valve proper, 7, is backed up by a valve-seating spring 10, which encircles the valve-stem 11 and is interposed-between the valve 7 and a nut or collar or other form of stop 12 on the stem. Each of the discharge-valves 8 is reversely disposed to open downward, as also shown in Fig. 2, said valve and its valve-seat being the counterpart of the intake-valve, but of course opening in a reverse direction. so as to allow the water to be forced from the cylinder downward into the hollow base, from whence it passes outward through the main outlet or supply opening 3. It will be observed that all of the intake-valves are located on the same side of the partition 4, while all of the discharge-valves are located on the opposite side of said partition.

Mounted in one cylinder is a verticallymovable float 13 of any suitable construc tion, either solid or hollow and of any suitable material adapting it to rise and fall within the cylinder, as influenced by the waterlevel. The float 13 is mounted to slide upward and downward on the stem. 14 and is also adapted to impart a vertical movement to said stem by reason of its coming in contact with stop-shoulders 15 and 16, located, respectively, at or near the upper and lower ends of the stem, said stop-shoulders being shown in the form of nuts or collars mounted fast on the stem and, if desired, made adjustable by means of binding-screws 1.7 or their equivalent.

At the lower end the stem 14 is mounted to slide up and down in a suitable guide 18,

while the upper end of said stem is connected pivotally at 19 to a lever 20, which is fulcrumed at its opposite end on a bracket 21.. Connected to the lever 20 at an intermediate point 22 is a link 23, which connects at its opposite end, at 24, to one arm of a lever 25, which is fulcrumed about centrally, at 26, beneath the head 27 of the cylinder. The extremity of the other arm 28 of said lever is pivotally connected at 29 to a counterbalance-weight 30, the lower end of which is mounted to move up and down in a guide 31 within the cylinder. It will thus be seen that as the float 13 approaches the upper and lower limits of its movements it will shift the stem 14 and throw the levers and their connections just described into operation, said levers being utilized-to control and shift the position of the auxiliary valve which admits air to the piston-valve.

The lever is provided about centrally with the extension or third arm 32, having a rounded head or extremity 33, which works in a socket 34, formed in the bottom of a slidable auxiliary air-admission valve 35, and it will be seen that as said lever is vibrated by the action of the float 13 the valve 35 will be moved lengthwise of its seat, so as to cover 1 and uncover inlet and exhaust ports leading l to and from the ends of the chest-cylinder of the air-piston valve, which will now be described.

.The air-piston valve is of substantially the same construction as the slide-valve shown and described in my Patent No. 743,927, granted November 10, 1903, for improvement in steam-engines, and comprises a cylinder or chest 36, in which is arranged a reciprocatory air-piston valve 37 of cylindrical form. The valve 37 is provided at one side with an inlet-port 38, which communicates with the air-inlet chamber 39, to which air is fed through a pipe leading off to the air-compressor. (Not shown.) In the opposite side of the valve 37 and adjacent to the opposite ends thereof are ports 40 and 41, adapted to be moved into and out of line with air-passages 42 and 43, one of said passages 43 lead ing directly into the pumpcylinder, upon the head of which the air-valve is mounted. The other air-passage 42 extends around that part of the valve-casing in which the valve 37 slides and delivers the air to a pipe 44, whichcommunicates with the head of the other cylinder, and the ports 40 and 41 are so arranged and related to the ports 42 and 43 that air is admitted alternately to the two cylinders, thus causing said cylinders to be alternately operated in such manner that as one cylinder is filling with water the other cylinder is discharging, and Vice versa. The piston 37 is also provided with an exhaustcavity 45, by means of which the air is admitted to an exhaust-passage 46 in the valvecasing and thence led outward to the atmos phere.

The valve-chest casing 36 is also provided in its base with air-inlet passages 47 and 48, which open into the chamber in which the valve 37 moves, said. passages 47 and 48 leading off to the same side of the air-piston valve and opening up at or near opposite ends of the seat 49, upon which the air-admission valve 35 slides, as shown in Fig. 5. Between the passages 47 and 48 is arranged an exhaust-port 50, and the valve 35 is provided with corresponding ports or cavities for alternately opening and closing the passages 47 and 48 and also the exhaust-passage 50 for the purpose of allowing air from the compressor to pass to and from the passages 47 and 48, and consequently to and from the ends of the piston-valve 37, for actuating the latter and also for allowing said air to exhaust through the passage 50.

At each end the valve-chest casing is provided with a lateral air-passage 51, leading into a chest-head 52, in which is arranged a check-valve 53, preferably in the form of a ball, which seats itself by gravity, another lateral passage 54 leading directly into the end of the chamber in which the piston-valve 37 moves.

It will now be seen that as the float in one saoe i pump-cylinder comes in contact with a stop on the stem 14 and moves said stem lengthwise the air-admissionvalve 35 will by means of the interposed operating connections be shifted on its seat so as to allow air passing in at 39 to find its way to one end of the piston valve 37. This causes the piston-valve 37 to shift in one direction or the other, so as to admit air either to the passage 42 or 43, and consequently to one pump-cylinder, which is supplied with air, and to allow the air to pass then to the other cylinder, the pump-cylin: ders being thus alternately operated. As the water is exhausted by the air-pressure from one cylinder the float 13 therein descends and, coming in contact with the lower stop 16, shifts the stem 14 and through the operating connections reverses the-position of the airadmission valve, thus also shifting the posi tion of the air-piston valve. This relieves the air-pressure of the pump-cylinder which has ust discharged and allows a fresh supply of water to enter said cylinder and elevate the float 13 preparatory to again admitting air to the top of said pump-cylinder.

It is also desirable to provide each of the cylinders with one or more hand-holes and hand-hole covers 55 and 56, arranged, respectively, in the top or head and side thereof in order to give convenient access to the valves and their seats for repair and cleaning.

The hollow base upon which the cylinder or cylinders are supported is inclosedthat is to say, said hollow base comprises top and bottom plates and sides which connect the top and bottom plates and form a water holding chamber which is divided by a partition into water-inlet and water-de1ivery compartments. This enables the apparatus to be set up at any desired point, either on a river-bank or at any convenient distance from the water, and a supply-pipe may be run to the river or other water-supply.

If desired, the apparatus maybe placed in a dry well or trench and the water-supply pipe run therefrom to the river or other source of supply and covered over. In the same manner a delivery-pipe may be connected to the hollow base and carried to any desired point of delivery. These pipes do not have to be disturbed in order to renew or examine the valves, this being accomplished through the medium of the hand-hole plates of the cylinder or cylinders. Again, in oilrefineries, for example, where it would be impracticable to lift such a heavy apparatus, which ordinarily weighs in the neighborhood of three or four thousand pounds, my apparatus may be placed adjacent to an oil-tank and the supply-pipe maybe carried into the tank, so as to conduct the oil therefrom into the hollow base of my apparatus, and such supply-pipe may be shifted as frequently as necessaryfrom one oil-tank to another. These instances are cited merely to show that it is not necessary to submerge the hollow base in the liquid to be pumped, such use of the apparatus being rendered practicable by reason of the fact that the said hollow base is inclosed, or, in other words, adapted to receive and hold liquid inreadiness to pass by the intake valves in the operation of the pump.

I do not desire to be limited to the use of any special number of pump-cylinders, as it will be apparent that the invention hereinabove disclosed may be utilized in connection with any number of cylinders, one or more. It will also be apparent that the construction hereinabove described is susceptible of considerable variation in form, proportion, and

minor details, which may accordingly be resorted to without departing from the principle or sacrificing any of the advantages of the invention.
